Relics and epics are hard to obtain special equipments with bonus attributes (Extra AP/MP/dmg etc) obtainable from several dungeons.

How to obtain a relic?

1) Obtaining 100 fragments of the same relic and combining them into the relic. The fragments can be linked or unlinked to make a relic, but linked fragments won't stack with unlinked fragments unless you link the unlinked fragments(not advised to do so).

2)Dropping the relic from HC dungeon boss. This is highly rare to drop a relic, but possible. It is not possible to drop a relic in a normal dungeon mode, so if the dungeon doesn't have a HC mode, it's boss can't drop the relic. Another exception is Flaxhid and Tormentor Dungeons - it is not possible to drop relics there on HC mode, only fragments.

How to obtain an epic?

1) via dungeon tokens, if the dungeon has the epic item in the token machine; 2) dropping it from the dungeon.
